Adding two numbers using functions

Lets get started

 
       


import java.util.* ; 
public class Main { 
    public static void main (String[] args) { 
        Scanner sc = new Scanner(System.in); 
        System.out.println("Enter size : "); 
        int size = sc.nextInt(); 
        // initializing array 
        int[] arr = new int[size] ; 
        // taking array inputs from the user  
        for(int i = 0 ;i
            if(sc.hasNextInt()){ 
                arr[i] = sc.nextInt() ; 
            } 
        } 
        // calling the function 
        System.out.println(doSomething(arr)); 
    } 
    // creating the function 
    public static int doSomething(int[] arr){ 
        int Ones = 0 ; 
        int Zeros = 0 ; 
        // counting numner of zeros and Ones  
        for(int i = 0 ; i < arr.length ; i++){ 
            if(arr[i] == 0){ 
                Zeros ++ ; 
            }else{ 
                Ones++ ; 
            } 
        } 
        // logic 
        if(Ones < Zeros){ 
            return Ones * 2 ; 
        }else{ 
            return Zeros * 2 ; 
        } 
    } 
} 
       

Output

  Enter size : 
  7
  0
  1
  0
  1
  1
  0
  0
  6

  Enter size : 
  2
  0
  1
  2
